Reflections for December

Product preservation and stable units for reflections into idempotent subvarieties

We give a necessary and sufficient condition for the preservation of finite products by a reflection of a variety of universal algebras into an idempotent subvariety. It is also shown that simple and semi-left-exact reflections into subvarieties of universal algebras are the same. It then follows that a reflection of a variety of universal algebras into an idempotent subvariety has stable units...

Reflections on Reflections

The graduate student workshop ''Buddhist Art: Objects and Contexts'' was an unusual event. Like Reflections of the Buddha, the exhibition it addressed, it was in constant dialogue with its physical setting, the singular Tadao Ando ¯ building home to the Pulitzer Foundation for the Arts, as the four sessions moved through the four galleries in changing light. The event was also distinguished by ...
